A fast lady on a moped . . . .

I can't figure out my bike.  It starts ok.  I can get it to idle.  On the kickstand, it idles, seems responsive.  I don't want to rev it too much (new motor) not broken in yet.  I can poke it into gear and start up the street . . . and as soon as I begin to accelerate - it starts (pretty violently) poppin' out the carb.  pop pop pop spit spit spit - Doesn't pop out the pipes.  Just the carb.  As soon as it's kinda "under a load" it starts doing it. WTF?

I've tried the following - with no change in the results

- Pushrods set (checked twice)

- Timing set (ran at different settings, no change)

- 2 different carbs with all types of 

different jetting (no change)

- Checked wire continuity

- Checked spark plugs (non-resistor) 0 ohms - perfect

- New fuel (twice)

- No Intake Leaks

I just changed the condenser this morning 
(but haven't tried it yet )

Maybe a have a cam that's off ?

Next thing will be the degree wheel I guess ?

Last night I was running (kinda idling) along in 2nd gear, and I noticed a lady on a moped was behind me.  I went to accelerate and speed up a bit, and the bike started popping out the carb - so she just pulled out and passed me.  Probably the only time a lady on a moped passed an XR/XLR performance motorcycle.  What an embarrassment.  As soon as I get this thing figured out, I want a rematch.  This sucks.
